Solar Neutrino Physics: Calibrating and Monitoring Borexino

这笔拨款将用于开发和建造专门用于液体闪烁探测器的操作测试和校准源，以及在几米路径长度上监测闪烁体特性的方法。这些要求与基于闪烁体的大型中微子探测器相匹配，在这些探测器中，放射性和防污染的安全性是至关重要的。特别侧重于开发Borexino太阳中微子探测器的校准和监测方案，其主要目的是测量太阳Be-7中微子通量。研究的主要途径是内部封装的放射源。该计划与Borexino合作的其他校准工作集成在一起。

This grant will fund the development and construction of specialized operational test and calibration sources for liquid scintillation detectors, as well as monitoring methods for scintillator properties at several meter pathlengths. The requirements are geared to match those of large scintillator based neutrino detectors where radiopurity and security against contamination are of paramount importance.Particular focus is given to developing aspects of a calibration and monitoring scheme for the Borexino solar neutrino detector, whose principle purpose is to measure the solar Be-7 neutrino flux. The primary avenue being pursued is an internal, encapsulated, radioactive source. The program is integrated with other calibration efforts of the Borexino collaboration.
